According to at least one aspect, embodiments herein provide a traffic light power management system comprising a power source, a first output, a service bypass unit and a power management unit. The service bypass unit is configured to receive AC power from the power source, convert the AC power to a first DC power in a first mode of operation, provide the first DC power to the first output in the first mode of operation, and provide the AC power to a power management unit in a second mode of operation. The power management unit is coupled to the service bypass unit, and is configured to receive the AC power from the service bypass unit in the second mode of operation, convert the AC power to a second DC power in the second mode of operation, and provide the DC power to the first output in the second mode of operation.

Power management unit for intelligent traffic system applications

A modular UPS system is provided wherein UPS systems may be constructed using a number of different frame components. In one example, a core UPS frame is provided that can accept different combinations of power and battery modules, and an extension frame is provided that can be combined with the core frame to provide a larger UPS system. According to one example, both the core and extension frame types may be used in either a standalone or rack-mounted configuration. Another aspect relates to packaging of UPS components such that the UPS frame need not include serviceable items. In another aspect, a rail system is provided that allows for easier installation of heavy components into rack-mount systems.
